Researchers identified rare variants of a gene involved in controlling the shape of cells and found them to be 2.7 times more common in left-handed people. While these genetic variants account for ...
In baseball, a right-handed pitcher's curve ball will break away from a right-handed batter and towards a left-handed batter (batting left or right does not indicate left or right handedness). While studies of handedness show that only 10% of the general population is left-handed, the proportion of left-handed MLB players is closer to 39% of ...
A number of factors make the identification of the genetic defects underlying human ectrodactyly a complicated process: the limited number of families linked to each split hand/foot malformation (SHFM) locus, the large number of morphogens involved in limb development, the complex interactions between these morphogens, the involvement of ...
LRRTM1 is the first gene linked to increased odds of being left-handed, when inherited from the father's side. [9] Possessing one particular variant of the LRRTM1 gene slightly raises the risk of psychotic mental illnesses such as schizophrenia, again only if inherited from the father's side. [9]
If the parents are both right-handed, in dizygotic and monozygotic twins there is a 21% chance of one being left-handed. If one parent is left-handed, in DZ and MZ twins there is a 57% chance of one being left-handed. If both parents are left-handed, it is almost certain one twin will be left-handed. [citation needed]
An older study found that left-handed people were better at "divergent thinking", and a more recent research cites lefties have better working memories and mental flexibility. 5. Don't get too ...
Only 10 percent of the population is left-handed. While there may not be many of them, being left-handed sure does come with some surprising perks! 14 things you never knew about left-handed people
A number of mutations of the LMBR1 gene, in dogs, humans, and mice, can cause polydactyly. [80] A 2014 report indicated that mice could also exhibit polydactyly arising from mutation in the VPS25 gene. [81] In cattle, it appears to be polygenic with a dominant gene at one locus and a homozygous recessive at another. [75]
